Recently i have been diagnosed as being sensitized to o positive blood/antinodies, this after i had my second child who is o positive and im o negative, however im confused, baffled and angry cos i had been given the anti d injection and it seems that this didnt work as it shoud have. does anyone had the same experience or had other children after being sensitized?

hi im 12 wks pregnant and have just been told im rhesus sensitive. Usually to become this way it takes 0- and 0+ blood to mix in a major way which in my case was with my last delivery of my baby girl who is 0+. I would say at some stage possibly like me when u had ur bubs ur blood probably mixed and even if they did give u the anti d injection it still wouldnt have been enough to stop u sentitising. i have seen other women with this problem and apart from having bloods every 2 wks and more scans than normal they all ended up with happy healthy babies after their little ones were treated which was usually blood transfusions and put in prem care as they were born from 28-36 wks.

Even me that was my understanding that the shot will counteract the antibodies however i searched about it and it works 99% which is alot but there is still that 1% that it doesnt work, and i think i am one of those 1%....

Your docs are right about being careful if having more children. As it was explained to me, when you have the Rh factor, your body views the baby as a foreign object that it has to get rid of (because of the incompatable blood types) and your immune system attacks the baby with the aweful results that you describe. It was my understanding that the shot would counteract this.

thanks alot for your reply, i have the rh factor like you too, i discovered this when i went to donate blood and the lab called me a few days later, that in my blood i found the anitbodies for o positive blood. Im o negative and my second baby was o positive and i only took the injection after he was born, and you said that you too the shot at 20 week too, i didnt even know that youre supposed to be given the shot during pregnancy too, i always taught they give it to you when the baby is born, the gynae and gp told me also that i have to be extremely careful not to have any more children, cos the possibility of having an o positive child is 50% and the baby can have many complications, ranging from jaundice, still born, brain injury and even dead after birth!!!!

I have what my docs called the Rh Factor and it sounds similar to what you're describing. This wasn't discovered until after I had a miscarriage (blood type had nothing to do with the miscarriage). I have A neg. blood and most babies have the same blood type as their dads (hubby is O positive). While preg. with my son I was given a shot at the 20+ week mark to counter my neg blood type. I don't remember what it was called. We were each given the shot again after he was born. I would have gotten another shot at the 30+ week point but my son was a preemie and I didn't get to that point (blood type had nothing to do with him being preemie). Now that I know I have this issue, it'll be monitored in any other pregnancies and I'll be given the shots again.
